Mandolin Strings are very important, as they have a big effect on your mandolin sound. The selection of mandolin strings is important, but also important is to know how to maintain your strings and when/how to change them. This article covers the above, explaining the following subjects in below paragraphs:

  1. Strings thickness, gauge and tension
  2. Strings wrap materials
  3. Strings core materials
  4. Strings construction
  5. Strings maintenance (cleaning)
  6. Strings replacement (when and how to change them)

A frequent question that I hear is “…which strings are right/best for my instrument?”. Although there’s no single answer to this question, the good thing is that a set of mandolin strings is rather inexpensive, costing from 5 dollars to 50, tops. Compare that with the cost of a set of cello strings, and you quickly understand that the mandolin allows you to experiment with different types and manufacturers of strings! Here is what you need to understand to select your set of mandolin strings:

Mandolin strings thickness (or gauge) and tension

The gauge is the thickness of a string’s diameter as measured in thousandths of an inch (e.g. 0.11, .16 etc.).

It is better to start with sets of strings with predefined gauges. As you experiment more, you may find that you prefer a specific chord (e.g. the E string or the A string) to be of a specific gauge. It is then when you start buying strings in pairs instead of sets.

As gauges come with many varieties, the industry quickly realized that it needed to categorize gauges to few categories to help buyers easier select strings. Thus, it started using three labels, namely light, medium and heavy, with heavy being the thicker ones. Concurrently, the tension term came into use. The mandolin strings gauge, described usually with the terms light/medium/heavy is directly related with the tension strings place on the instrument typically labeled as low, middle, high.

How to select which gauge/tension to use?

Mandolins come with a string specification, i.e. a recommendation from the luthier of the gauge/tension to use, as using heavier gauges than what the mandolin was designed for, may damage the mandolin neck on the long run. Nevertheless, as heavier strings place more tension they tend to project more powerful sound, and are therefore preffered by mandolin soloists in concerts. In such cases, the expert advise of the luthier should be asked.

Also note that heavy strings are harder to play; you need to apply more force on a fret in order to play the note. This makes playing fast more difficult and as you understand you must find a balance between speed and sound power.

Finally some mandolin types may be damaged with heavy strings, as for example old bowlback mandolins. Newer mandolins like the carved ones used in the United States are made stronger, and therefore typically use heavy strings, while flatback use medium strings.

So the conclusion is:

“…use heavy strings for more powerful sound but only if you are sure it will not damage your instrument!”

Mandolin Strings construction – Round-Wound, Flat-Top and Silk-Steel

 The mandolin strings construction can have a dramatic impact on feel and playability.  For example I prefer flat top strings, as fingers just slide up and down the fretboard with ease. In my case this is not only related with speed but also with sound. Sliding notes on flat top strings produce a very impressive sound! On the other hand, flat tops sound tends to be “darker” than other types, so…

“…It is advised to experiment with different types of strings, till you decide the type of strings that suits you best.”

Round wound strings are the most popular and are offered by almost all manufacturers. They deliver a textured feel most players are familiar and comfortable with. They are also the cheaper ones.

Flat tops are constructed from finished round wound strings. They are further processed to carefully flatten the tops of the windings through a polishing technique. Flat Tops are known to deliver a smoother feel and reduced finger noise with the flexibility and tension of a round wound string and for this reason are sometimes preferred by professional artists for recording. They are also used by classical orchestras to minimize “noise” picked up by microphones during live performances.

Silk-Steel are made of silver-plated copper wrap wire interwoven with silk-like fibers for soft, easy fingering and a mellow tone. They are preferred by many folk and finger style players.

How to select which construction to use?

Flat tops are typically more expensive and have less “noise” when moving on the fretboard, making them ideally for recordings. But note, they tend to produce a less bright tone, so everything comes to personal preference!

Mandolin strings materials

Here is a nice image (Source: D’Addario) that shows how the string is constructed by a core and a wrap wire.

Mandolin Strings Wrap Material

Strings wrap material is important. Electric and acoustic mandolin strings are typically made using a steel core wire with a “wrap wire” wound onto the core.

The type of alloy used as the wrap wire determines the tonal quality of the strings. It affects tone (from mellow to bright) as well as projection. It also affects playability (combined with construction) and durability (combined with coating).

Five types are typically used as following (from mellow to bright). Here’s a quick reference guide:

  • Silver-plated Copper – Typically used for classical and folk due to their soft, comfortable feel and warm, mellow tone
  • Phosphor Bronze – pioneered by D’Addario in 1974, they are known for their full, rich, acoustic tone. Phosphor bronze provides a warm (mellow), but at the same time bright tone.
  • Brass (or 80/20 Bronze) – 80/20 Bronze (also referred to as brass) acoustic instrument strings provide a brighter tone than phosphor bronze. They have great acoustic clarity coupled with extra-bright, loud tone. 
  • Stainless Steel – provide an even brighter, more cutting tone than brass strings. They’re generally used on electric instruments, but can be used on acoustic instruments as well.
  • Nickel – provides great overall tone and sound and is used by best-selling strings of electric instruments. For acoustic instruments not preferable.

The best idea here is to experiment with all types, till you find which type you prefer. Note also that not all brands are the same. That means your experimentation may take … more time!

The type of alloy used as the strings wrap wire determines the tonal quality of the strings. But what does this mean?

Some mandolins are made very bright, so you may consider using strings producing a warm tone in order to have the result you like, or vice versa. Also some types of music are better performed with a particular sound. Take jazz for example, and think the sound you expect to hear from an instrument. Is it mellow or bright? If it is mellow, then yes, Phosphor Bronze may be better for playing jazz with a mandolin.

So my advise is:

“…experiment with different types of strings, till you decide the type of strings that produce the best sound with your mandolin for the particular type of music you are playing.”

Mandolin Strings Core Material

Mandolin strings tend to be steel core (and mainly solid steel). All options are:

  • Nylon core
  • Spiral steel core
  • Braided steel core
  • Solid steel core.

There is no reason to spend more time on the core material, as what is really important is the wrapping material of the mandolin strings.

Mandolin Strings end

The string end term is used to describe how the string is attached to the tail piece.

There are two options here, ball-end strings and loop-end strings.

You have to select the one that fits to your instrument. How can you do that?  The pictures below will help you distinguish the two types, and select the right one.

Mandolin Strings Maintenance

How Often Do I Need to Change Strings?

Replacing old mandolin strings with a new set will in general improve the sound and playability of your instrument. A rule of thumb is to change strings every 1-3 months, but that depends on playing frequency. There are performers that prefer to install a new set of strings in each performance, but most players change strings when they notice some issue. So my advise is…

“…replace your mandolin strings when you notice tuning problems or less bright sound; in any case try to change strings every 3 months”

What Are Some Common Mistakes That Damage Strings?

If you put strings on an instrument which is smaller than the one which the string is designed for, there will be a considerable loss of tension and sound quality. Apart from this, the thicker playing length of the string will end up being wound around the tuning peg, which – especially with thicker strings – will result in damage to the core, loss of tonal quality and strings breaking. This is one of the most common mistakes.

If you put strings on an instrument which is larger than the one the strings are designed for, e.g. on a large viola, it will have the same effect as tuning the string to too high a pitch, or starting tuning from the highest string to lowest instead of the other way around. Doing this even once can severely fatigue the string or break it.

Sharp edges on the bridge, the nut or the tailpiece will damage the string, and can lead to breakage.

The same can happen if the channels in the nut are too narrow, so these should be of sufficient width and prepared with a little graphite from a soft pencil.

Another mistake to avoid when re-stringing the instrument is improperly winding the string around the tuning peg. The correct number of windings is between four and five, without any bending of the string between nut and tuning peg and without jamming it against the peg box.

Why Is Strings Length Important?

String length is defined as the sum of three distances:

  • from the ball or loop end to the bridge
  • from the bridge to the nut (i.e. the string‘s vibrating length)
  • from the nut to the tuning peg.

When playing custom instruments, the scale of the instrument may vary. It is then when you need to measure the scale (from bridge to nut) of your instrument but also the distance from nut to tuning peg and string end to the bridge, summarize them and use the result as your guide to select custom strings with the proper length.
